I'll be damned. How this works doesn't make any sense to me. To me that 
reads; from the 1 position upto but excluding the 1 position, put a value (2 
in this case). 

The same can be done with something like array[1,0]=2 as was pointed out by 
Rennex on IRC #ruby-lang. To me that reads; from the 1 position with a length 
of 0 assign the value. I'm almost reading this as a 1/2 element index - from 
a readability point of view to me it just doesn't make sense.

Can anyone help me understand it from a readability POV? Some on irc have 
tried to explain it in implementation terms but when I'm coding in Ruby I'm 
not thinking about how it is understood in Ruby, more about how it reads in 
Ruby. Any help is welcomed. Thank you.
